Coastal SoCal. No HVAC or insulation needs.

Not a true basement, but a detached building built into a hillside such that most of it is underground.

The building walls are concrete, and I want to frame it out to build plywood walls for ease of mounting french cleats, storage racks, etc. vs. bolting into the very old concrete.

I plan on painting the concrete with a couple coats of Drylok and doing the framing with pressure treated lumber. Is that enough, or should I also install plastic/Tyvek/some other moisture barrier between the studs and the wall? Only if they touch? If so, what’s the easiest way to do that? I probably have to frame the wall in place due to space constraints.
